Minisci reaction of heteroarenes and unactivated C(sp)-H alkanes a photogenerated chlorine radical

Here, an efficient Minisci reaction of heteroarenes and unactivated C(sp 3 )-H alkanes was achieved using an inexpensive FeCl 3 as a photocatalyst. The photogenerated chlorine radical contributed to the HAT of C-H and subsequently initiated this reaction. Surprisingly, salt water and even seawater can act as a chlorine radical source, which provided an enlightening idea for future organic synthesis methods.
